1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

A simple and rapid electrochemical method based on a composite of cadmium telluride quantum dots (CdTe QDs) and MXene is developed for the simultaneous determination of rutin and quercetin in food samples. The CdTe QD-MXene composite is synthesized via the in situ growth of CdTe QDs on MXene, which serves as a carrier and enhances electrical conductivity. Incorporating CdTe QDs into MXene interlayers effectively prevents agglomeration in MXene and provides more active sites for electrochemical determination. The developed electrochemical method can successfully determine rutin and quercetin, both individually and simultaneously, in aqueous solutions while achieving high stability and selectivity. Notably, the prepared sensor exhibits limits of detection of 3.300 × 10
